摘　　要：以研制独立光伏系统逆变器为背景对具有高频DC/DC中间环节逆变器进行了研究和设计,采用了FB-PS-PWMZVS技术,引入了新一代软开关控制器UCC3895,提出了互补型脉宽调制(CPWM)的单极性正弦逆变概念,并将SG3525引入SPWM逆变控制中。实验和仿真验证了设计思想和设计方案。The inverter with high frequency link is studied for the stand-alone PV system. The FB-PS-PWM ZVS technology is adopted, the new type of SMPS controller--- UCC3895 is introduced into high frequency DC/DC link, the concept---complementary PWM unipolar sine inverting is put forward, and the controller--SG3525 is used in SPWM control. The design idea and scheme are tested and verified.
